Answers |Actual Complete Exam |Already Graded A+
chemical and physical properties of water ✔Correct Answer--Excellent solvent• High
melting/boiling temperature• Exists in solid, liquid, and gas form• Surface tension (remember
'sticky' molecules)
atoms ✔Correct Answer-cannot be broken down by smaller chemical means*building blocks
molecules ✔Correct Answer-chemically bonded atoms; formed when electrons are shared or
borrowed
covalent ✔Correct Answer-water molecules form ____ bond between hydrogen and oxygen
hydrogen bonding ✔Correct Answer-Bonds between hydrogen atom and oxygen atom of
another water molecule
surface tension ✔Correct Answer-the force that acts on the surface of a liquid and that tends
to minimize the area of the surface
temperature ✔Correct Answer-a measure of how fast the particles in an object are moving
heat ✔Correct Answer-a measure of the total amount of kinetic energy due to molecular
motion
heat capacity ✔Correct Answer-A measure of the heat energy required to increase the
temperature of a given substance by a given amount
sensible heat ✔Correct Answer-The heat energy that causes a change in temperature of a
substance but does not contribute to a change in state
solid ✔Correct Answer-ordered, structured strong bonds
liquid ✔Correct Answer-able to form or destroy hydrogen bonds
water vapor ✔Correct Answer-no bonds, rapid motion (collision)
latent heat ✔Correct Answer-the heat required to convert a solid into a liquid or vapor, or a
liquid into a vapor, without change of temperature.
decreases ✔Correct Answer-if volume increases, density ___
, salinity ✔Correct Answer-A measure of the amount of dissolved salts in a given amount of
liquid
polar ✔Correct Answer-water is a ______ molecule
3.5% ✔Correct Answer-our oceans have a salinity of ___
recall ions ✔Correct Answer-atoms or molecules with a net charge
cations ✔Correct Answer-positively charged ions
anions ✔Correct Answer-negatively charged ions
sea salts ✔Correct Answer-chloride, sulfate, sodium, calcium, potassium, magnesium
why seawater doesn't match river water ✔Correct Answer-substances in the upper mantle
released during outgassing through volcanoes / rift vents
processes that decrease seawater salinity ✔Correct Answer-precipitation, runoff, glaciers
melting, sea ice melting
processes that increase salinity ✔Correct Answer-sea ice forming, evaporation
pycnocline ✔Correct Answer-a zone in which density increases with depth, containing about
18% of all ocean water
deep zone ✔Correct Answer-contains about 80% of all ocean water. There is little change in
density throughout this layer.
thermocline ✔Correct Answer-a steep temp gradient in a body of water such as a lake,
marked by a layer above and below which the water os at different temp
halo cline ✔Correct Answer-a layer of water in which the salinity changes rapidly with the
changes in depth
estuary ✔Correct Answer-A partly enclosed coastal body of brackish water with one or more
rivers or streams flowing into it, and with a free connection to the open sea.
more ✔Correct Answer-warm air can hold ___ water vapor than cool air
influence air density ✔Correct Answer-temp pressure and water content
why the angle of the sun matters ✔Correct Answer-the same amount of light is being spread
over a larger area
